Explore Jeep J-3800 service references for front suspension work, axle projects and engine restoration at Black Ops Auto Works. Compare named Rancho and ARB entries alongside bearing, sealing and smaller engine-service pieces. Coordinate each purchase around the installed assemblies and the builder’s planned work.
Suspension and Differential Project Choices
Compare Rancho front shocks by complete J-3800 coverage, mounts and current suspension configuration, with a steering stabilizer selected separately for its own mounting arrangement. For an ARB differential project, identify the installed axle and match the exact Dana 44 or Dana 60HD application, spline and ratio requirements. Plan supporting installation pieces for each project independently.
Bearings, Sealing and Cooling Service
Choose King main bearings for the actual engine and measured journals, with STD or undersize selection confirmed by the builder’s machining and clearance requirements. Check Clevite and COMP Cams components against the same complete engine-build plan. Match Omix sealing or distributor-service pieces and the Edelbrock thermostat by their individual dimensions, interfaces and application.
Driveline and Smaller Restoration Pieces
Omix axle gaskets, steering-knuckle seals and a greaseable driveshaft joint address separate service points. Match actual axle or shaft identity and component dimensions. Mounts, switches and broad floor-protection entries require their own installation, protected-area and supplied-content review.
Choose Your Part
- Choose suspension, an axle project or defined engine restoration.
